This book can decide if you're judging it before you've checked out its contents. There's a face-tracking camera onboard and a screen embedded into the cover for potential readers to see their faces get approved or denied, depending on expression.

On today's show, we get warm and fuzzy about a low-cost prosthetic helping a teen play guitar, see gamers race down a VR hill against an athlete speeding down the real thing, watch one particular book tell if you're judging it by its cover, and enjoy a drone made to look like the Millennium Falcon.

The guy who built the Millennium Falcon drone is back with another "Star Wars"-themed drone creation. If you see this TIE Interceptor drone coming your way, you'd better hope your hyperdrive is operational.
